Hi,
At the tail end of a vacation to Mexico I started to get these weird electrical jolts in my right arm and hand. It only happened with movement (up and down stairs, Turing my head sometimes). This was 2.5weeks ago and about 10 days ago it started getting worse.

It seems to be movement based and I get the electrical shock feeling and a very strange dizziness. It happens all the time and mostly when I turn my head. If I lay still...no such sensations.

I did a lot of swimming in Mexico and just before I left I had a bit of a wipe out and bruised a rib. I am wondering if this could be as simple as a pinched nerve that got worse with all of the exercise?
